SARS-CoV-2 is the virus responsible for the COVID-19 pandemic. The acute infection is characterised not only by respiratory symptoms, but also by multiple systemic manifestations, including neurological symptoms. Among these, headache is a frequent complaint. As the pandemic progresses and the population of patients recovering from COVID-19 grows, it is becoming apparent that the headache present in the acute stage of the infection may persist for an indeterminate period, becoming a major problem for the patient and potentially leading to disability. In this review we describe the pathophysiological and clinical aspects of persistent headache after COVID-19 based on the information currently available in the literature and the authors’ clinical experience.

Objective To assess the quality of the therapeutic approach in Specialized Headache Units in Spain. Methods An observational (prospective) study was conducted. Anonymized data of 313 consecutive patients during a defined period of time were analyzed and a comparison of performance in 13 consensual quality indicators between Specialized Headache Units and neurology consultations was calculated. Specialized Units and neurology consultations represented the type of provision that Spaniards receive in hospitals. Results The consensus benchmark standard was reached for 8/13 (61%) indicators. Specialized Headache Units performed better in the indicators, specifically in relation to accessibility, equity, safety, and patient satisfaction. Patients attended in Specialized Headache Units had more complex conditions. Conclusion Although there is variability among Specialized Headache Units, the overall quality was generally better than in traditional neurology consultations in Spain.

ObjectiveThe coronavirus disease 2019 (COVID-19) has spread worldwide since December 2019. Neurologic symptoms have been reported as part of the clinical spectrum of the disease. We aimed to determine whether neurologic manifestations are common in hospitalized patients with COVID-19 and to describe their main characteristics.MethodsWe systematically reviewed all patients diagnosed with COVID-19 admitted to the hospital in a Spanish population during March 2020. Demographic characteristics, systemic and neurologic clinical manifestations, and complementary tests were analyzed.ResultsOf 841 patients hospitalized with COVID-19 (mean age 66.4 years, 56.2% men), 57.4% developed some form of neurologic symptom. Nonspecific symptoms such as myalgias (17.2%), headache (14.1%), and dizziness (6.1%) were present mostly in the early stages of infection. Anosmia (4.9%) and dysgeusia (6.2%) tended to occur early (60% as the first clinical manifestation) and were more frequent in less severe cases. Disorders of consciousness occurred commonly (19.6%), mostly in older patients and in severe and advanced COVID-19 stages. Myopathy (3.1%), dysautonomia (2.5%), cerebrovascular diseases (1.7%), seizures (0.7%), movement disorders (0.7%), encephalitis (n = 1), Guillain-Barré syndrome (n = 1), and optic neuritis (n = 1) were also reported, but less frequent. Neurologic complications were the main cause of death in 4.1% of all deceased study participants.ConclusionsNeurologic manifestations are common in hospitalized patients with COVID-19. In our series, more than half of patients presented some form of neurologic symptom. Clinicians need to maintain close neurologic surveillance for prompt recognition of these complications. The mechanisms and consequences of severe acute respiratory syndrome coronavirus type 2 neurologic involvement require further studies.

Background Headache is one of the most prevalent diseases. The Global Burden of Disease Study ranks it as the seventh most common disease overall and the second largest neurological cause of disability in the world. The “Do Not Do” recommendations are a strategy for increasing the quality of care and reducing the cost of care for headache. This study aimed to identify specific low-value practices in headache care, determine their frequency, and estimate the cost overrun that they represent, in order to establish “Do not Do” recommendations specifically for headache by consensus and according to scientific evidence. Methods This was a mixed methods research study that combined qualitative consensus-building techniques, involving a multidisciplinary panel of experts to define the “Do Not Do” recommendations in headache care, and a retrospective observational study with review of a randomized set of patient records from the past 6 months in four hospitals, to quantify the frequency of these “Do Not Do” practices. We calculated the sum of direct costs of medical consultations, medicines, and unnecessary diagnostic tests. Results Seven “Do Not Do” recommendations were established for headache. In total, 3507 medical records were randomly reviewed. Low-value practices had a highly variable occurrence, depending on the hospital and type of headache. Overall, 34.1% of low-value practices were related to treatment, 21% were related to overuse of imaging in consultation, and 19% were related to emergency care. The estimated cost of low-value practices in the four hospitals was 203,520.47 euros per 1000 patients. Conclusions This study identified low-value headache practices that need to be eradicated and provided data on their frequency and cost overruns.
